It happened Friday morning at police officers' convention near Harrisburg, where 300 narcotics officers from Pennsylvania and Ohio were gathered.

John Comparetto, a retired NYPD Lt., says as he came out of a stall in the men's room, a man was pointing a gun in his face and demanding his money.

Comparetto gave up his money and cell phone. But when the man fled, Comparetto and some colleagues chased him. They arrested 19-year-old Jerome Marquis Blanchett of Harrisburg as he was trying to leave in a taxi.

When a reporter asked Blanchett for comment as he was led out of court, he said, "I'm smooth."
